有人知道GDI+怎么用！

[yuanhen]

bcb6下有gdiplus.h，但是不能用，include后编译会出很多的问题！


有人知道吗？

用c#时用过的。bcb里没用过。

我就是想知道bcb里怎么用，虽然有gdiplus这个头文件但是没法用！

以前有帖子说明这个问题，
用implib生成lib然后使用

If you start a new project, make sure you have defined the symbol STRICT
globally. In order to define STRICT for all modules of your application,
simply (from the IDE) you have to open the window Projects->Options, then
choose Directory/Conditional tab. Now, you have to add STRICT in "Conditional
defines" inside the "Conditional" group box. If you are debugging your
application (i.e. you are compiling for debug), probably you have to add a
semicolon after the existent symbol _DEBUG before add the symbol STRICT (i.e.
you should read something like this: _DEBUG;STRICT). Also, remember you have
to include <algorithm>, using std::min and using std::max *before* including
<gdiplus.h>:

...
...
#include <algorithm>
using std::min;
using std::max;
...
...
#include <gdiplus.h>

Remeber also you have to add the library you have created with implib, into
your project.

some sample code below:

//---------------------------------------------------------------------------

#include <vcl.h>
#pragma hdrstop
#include <algorithm>
using std::min;
using std::max;

#include "Unit1.h"
#include <gdiplus.h>
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;

using namespace Gdiplus;

//---------------------------------------------------------------------------
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
GdiplusStartup( &gdiplusToken, &gdiplusStartupInput, NULL );
}
//---------------------------------------------------------------------------
__fastcall TForm1::~TForm1(void)
{
GdiplusShutdown( gdiplusToken );
}
//---------------------------------------------------------------------------
void __fastcall TForm1::PaintBox1Paint(TObject *Sender)
{
Gdiplus::Graphics g( Canvas->Handle );
Pen pen( Gdiplus::Color( 255, 0, 0, 0 ), 3 );
g.DrawLine( &pen, 50, 50, 500, 50 );
g.DrawPie( &pen, 50, 50, 200, 200, 225, 90 );

SolidBrush sbrush( Gdiplus::Color( 128, 255, 0, 0 ) );
LinearGradientBrush gbrush(
Gdiplus::Point( 50, 100 ),
Gdiplus::Point( 250, 200 ),
Gdiplus::Color( 255, 255, 0, 0 ),
Gdiplus::Color( 128, 0, 0, 0 )
);
g.FillRectangle( &gbrush, 50, 100, 200, 100 );
}
//---------------------------------------------------------------------------
